How this service works

FMCSA motor-carrier (trucking/bus company) safety profile. Pass dot (USDOT number) for the full record: legal/DBA name, state, interstate/intrastate operation, operating-authority status (allowedToOperate), FMCSA safety rating, fleet size (drivers + power units), crash history (total/fatal/injury/tow-away), roadside-inspection history with driver + vehicle out-of-service rates, and the CSA BASIC measures (Unsafe Driving, Hours-of-Service, Driver Fitness, Controlled Substances, Vehicle Maintenance, Hazmat, Crash Indicator) with violation counts. Or pass name to search → matching carriers with their DOT numbers. Free, public-domain US DOT data (keyed). For commercial-auto/freight underwriting, broker/shipper vetting, and vendor due diligence — the authorization + safety record an agent can't get from training.

Output

Returns a structured JSON object containing: carrier identity (legal name, DBA, DOT number, operation type, status), safety rating and date, whether the carrier is allowed to operate, crash counts (fatal, injury, towaway, total), inspection totals and out-of-service rates for drivers and vehicles, and BASIC category scores (percentile, measure value, violation counts, intervention threshold status). In name-search mode, returns a list of matching carriers with their DOT numbers.

Example use cases

Example prompt

“Can you pull the FMCSA safety profile for USDOT number 264184 — I want to see their safety rating, crash history, inspection out-of-service rates, and whether they're currently allowed to operate?”

Technical details

Endpoint

GEThttps://2s.io/api/gov/carrier-safety?utm_source=zero.xyz

When to prefer

Use this endpoint when you need authoritative, government-sourced safety data for US motor carriers — including safety ratings, BASIC scores, crash history, and operating authorization. Prefer this over general business lookup endpoints when the subject is a trucking or freight carrier and regulatory compliance is the concern. Ideal for freight vetting, logistics partner due diligence, insurance underwriting, or compliance checks.

Side effects

DOT number not found in FMCSA database — found: false returned
Carrier name search returns zero matches — empty matches array
Invalid DOT number format causes query failure
Name search limit out of range (must be 1-50)
FMCSA upstream source temporarily unavailable
